Patented July ll, lull lb all whom it may concern:

Be it known that l; l iusn Du l /lrnn a c1t1- zen oi' the llnited States of America, and a lll lllr

resident of Picher, in the county oi Ottawa, State of Oldahonaa have invented certain new and useful linprovenients in Apparatus for loncentrating Ures, of which the fol lowing is a true and exact description, rel.- erence being had to the accompanying drawings, which form a part thereof.

My present invention comprises improvements in apparatus for concentrating ores by the so-culled froth or flotation process and the general object of my invention is to provide an eflicient apparatus for the purpose specified, characterized by its simplicity of construction and ease and eficiency of operation, and particularly by the easy man- 'ner in which the rate of travel of the ore and its liquid vehicle through the apparatus maybe regulated.

The various features of novelty which Figure l is an elevation partly in-section" on the line 1-l of Fig 2. i

Fig. 2 is a plan view olthe apparatus with parts broken away and removed.

Fig. 3 is an and Fig. t isle partial section ,on the line -l.4 cl Fig. 2, The apparatus shown in the drawings comprises a row of vertical cells A to A inclusive, the walls of which. may advantageously be formed as shown, by a suitably disposed wooden cribbing. At each side oi this row of cells is located a spitalrasten or lroth chamber B, each of which is divided up into a series of cells B", B2 B B 18 and B by correspondingly located partition walls ll h ills slnwrln there is one division. wall fe centrally disposed with respec. to each of the cells. it A A], it? and fl in each spitzhastcn B. The spitsltasten chsnr hers lzl communicate with the cells it and A, A, A A and end view of the'apparatus,"

A through bottom ports A and A, respectively, and through upper ports A and A respectively. Similarly bottom ports A, A A A and Ji and upper ports A connect the Spitzkasten chambers 13 to the cells A and A; the spitzkasten chambers B to the cells A and AM; the spitzkasten chambers B to the cells A andrl the spitzkasten chambers B to the cells A and A and the spitzkasien chambers B to the cells A" and A. As shown, each of the ports A99, A etc, A, A, etc extends thefull width of the cell into which it o ens, F represents the ore or slime supply pipedischarging into the upper end of'thc chamber A, and G represents the gangue discharge pipes opening from. the bottoms of the spitzkasten chambers B The rate of discharge through the outflow pipes G may bemegulated by means of the simple plug cocks G with which the outflow pipes G are provided.

Mounted in each of the vertical cells, ex cept cells A and A is a rotating. agitator or heater C carried by a vertical spindle C, which is provided at its upper end with a pulley C Each of the spindles C is journaled at its upper end on an upper support ing beam- (3 and also passes through a bearing block C" which extends across the top of the corresponding vertical cell and supports a step bearing for the spindle.

Each of these hearings comprises a collar 0 adjustably secured to' the corresponding spindle C, as by a set screw 6, as indicated inllig, l, and a bearing plate O carried by the corresponding block (1 and against which the lower end of the corresponding spindleoollar hears. The vanes of each agitator C are slightly inclined and the agitutor is rotated in such direction that. it tends to create an upward flow through the vertical cell in which it located. The

agitating-and froth producing. effect of the agitators C may be individually adjusted by raising and lowering the collars C Bearings are provided at the outer edge of each froth chamber B for the usual rotatable froth transferred-rs E which sweep the froth with the metal held thereby into the froth collecting channels l) at the sides of the chambers "he ore or slime enter-in cell A. passes out of the latter into the adjoining cell A through a port locatedas indicated at A lllll eonnecting' the lower ends of these cells, and

passes from the cell A into the cell. A through an upper port located at A. From the cell A the slime passes into the lower -5 end of the cell A through a port located at A .The oily agent for securing the desired froth effect is mixed with the slime either prior to the introduction of the latter into the chamber A, or in the latter cham- ".10- her. The supply through the pipe F and the discharge through the cocks G are so regulated that the liquid level, in the cells A to 2A and in the spitzkasten B, is, kept below the froth collecting channels D at the i sides of the chambers B. p

' i In the preferred normal mode of use of my partments B and so on. The flow of the :2, l

liquid along this horizontal serpentine path, If; supplemented by the agitating effect of the Theaters 0 prevents the heavier particles of ore and gangue from collecting at and clogging the apparatus at any point. In each of the cells A to A the corresponding agitator beats more or less of the oily menstruum to afroth which as it rises to the top of the cell, carries with it more or less of the metal to be recovered. The froth passing into the upper portion of each spitzkasten compartment through the corresponding upper ports A to A is wholly or mainly removed j therefrom in normal operation by the cor- "?responding froth transferrer E since there is j 40' no appreciable tendency of the froth to pass from one spitzkasten compartment into another. The joint regulation of the rate of '---supply through the pipe F and the rate of withdrawal through the outlets G not only regulates the rate of liquid and ore flow through the apparatus, but also the liquid --level therein and thereby contributes materially to the efliciency of operation under varying conditions/ While in accordance with the" provisions of the statutesI have illustrated and described the best form of my invention now known to me, it will be apparent to those skilled inthe art that changes may be made in the form of my invention without departing from its spirit, and that some features of my invention may sometimes be used to advantage without a corresponding use of other features of the invention.
